The biggest problem in the country gun wise is fully illustrated in the article. Lack of enforcement of gun laws on the books and judges being complete fucking dumbasses. How many times have you seen a multiple time felon out committing murder? It's never ending. The other part of the equation is our national disgrace of a mental health strategy. Not enough beds, still a stigma and a severe lack of concern or understanding by authorities including politicians.
The latter would rather garner votes from equally stupid voters.
